Catalina CouponsPosted on February 14, 2011Catalina coupons (sometimes called “checkout coupons” and often referred to as “CATs” on couponing sites) are the secret weapon of extreme couponing that often allow you to get free or nearly free products at the grocery store — and sometimes even turn buying food into a money making opportunity. Catalina coupons are named after the company that distributes them and are coupons which you sometimes receive with your receipt at the grocery store. Catalina coupons do not actually come from the register (the advertisements on the back of some register receipts are completely different), but from a little white box located next to the register called, appropriately enough, a Catalina machine.Most Catalina coupons are regular manufacturer coupons and are for a certain dollar amount off the purchase of a specific product although they can be store specific coupons. Catalina coupons are triggered when you buy certain products or combination of products. For example, if you buy a package of Pampers diapers, you might get a Catalina coupon for a certain amount off Huggies diapers.
